Path Tracer
======================

University of Pennsylvania, CIS 561: Advanced Computer Graphics, Course project
------------


Features :
------------

- Normal Map

- Diffuse are light, point light, spot light, infinite light(Environment Map)

- Different materials (Metal, ChromMirror, glass, plastic, etc.)

- Acceleration : BVH / Kd-Tree

- Lens-based Camera

- Implicit Surface Rendering

- Photon Mapper (may take super longer time, but render converges quite well!)

- Volume Rendering



Rendered Images
------------

- Volume Rendering :

  Original Photon Mapper render

  thin & thick white fog volume render 

  ![](./renders/hw11_rendered_images7_160000.png)  ![](./renders/hw11_rendered_images7_360000.png)  


  final volume render we get

- Photon Mapper : Rainbow Box

- Implicit Surface Rendering using Ray-marching

- Lens-based Camera with Lens Radius = 1.0 , 5.0, 10.0

  ![](./renders/hw9_thin_len_60_lensR_10.0_f_30.png)



- Complex model rendered within just few minutes (general <10min depends on your computer)with BVH/Kd-Tree and more the 1 hour at least without it.

  900 ssp MIS Glass dragon (around 3min rendering time) / 900 ssp MIS Happy Buddha (around 4min rendering time)

- (This one actually a little bit light / uv problem, but I think it's a cool mistake)

- Mountains (Texture + Normal Map + Environment Map)

- Wahoo's War(several different color point lights)

  ![](./renders/hw10_66_900SampleMIS.png)


- Evil Wahoo..(OK, it's just a light problem, too dark)

  ![](./renders/54_uvProblem.png)
